[DSS DRV][Bug Fix][PDK-5040]Display stops working if two pipelines are started back to back
- Issue:
- When two display pipelines (connected to the same overlay) are started back to back by calling FVID2_Start() twice, pipelines do not start and does not display anything.
- Same is observed for 2 LCDs
- Resolution:
- Second start has to wait for a VSYNC to come from first pipeline before starting
- Fix:
- We should not allow pipelines to be started back to back until the first vsync callback of pipeline comes.
- Wait for semaphore before starting second pipeline
